Essential, it works Rated 5 out of 5 stars

Need this for FF3 if you want more than one row for your bookmarks toolbar. The previous chrome that did this for ff2 does not work anymore, and I tried 3 different versions of new chrome that had various problems (broken drag-n-drop, fixed-pixel height). Even the ff2 chrome had a weird problem where your multiple rows would sometimes collapse into one if any particular row was long enough; it seemed to be around the point where wrapping was needed, and I had to adjust the length by renaming some bookmarks longer or shorter - a pain. Anyway, this extension does not seem to have the same problem - thanks!

This review is for a previous version of the add-on (2.1).
